非平衡稳态的精确等式和热力学关系

Exact equalities and thermodynamic relations for nonequilibrium steady states

Teruhisa S. Komatsu, Naoko Nakagawa, Shin-ichi Sasa, Hal Tasaki

摘要:

本文研究在非平衡条件下,物理系统中使一个非平衡稳态(NESS)变为另一个NESS的热力学操作。我们通过一个合适的马尔可夫跳过程的系统建模,并根据外部代理不同的马尔可夫过程的参数的协议处理热力学操作。然后,我们证明,除其他关系,一个NESS版本的Jarzynski平等和扩展克劳修斯关系。后者可以作为NESS热力学的一个出发点。我们还发现,相应的非平衡熵有一个微观表示的对称香农熵的系统中的微观描述的状态涉及“动量”。所有结果在数学上都是严格的。

英文摘要:

We study thermodynamic operations which bring a nonequilibrium steady state (NESS) to another NESS in physical systems under nonequilibrium conditions. We model the system by a suitable Markov jump process, and treat thermodynamic operations as protocols according to which the external agent varies parameters of the Markov process. Then we prove, among other relations, a NESS version of the Jarzynski equality and the extended Clausius relation. The latter can be a starting point of thermodynamics for NESS. We also find that the corresponding nonequilibrium entropy has a microscopic representation in terms of symmetrized Shannon entropy in systems where the microscopic description of states involves "momenta". All the results in the present paper are mathematically rigorous.
